SPECIFICATION forming part of Letters Patent o. 598,423, dated February 1, 1898. Application ledV September l, 1896. Serial No. 604,541. (No model.)

To OLZZ wwt it may con/cern); Be itknown that 1I, `Iltrnnr. KLEIN, a citi- Zen of the United States, residing at' Glen, in the county of Sioux` and State of Nebraska, have invented certain new and useful Improvements in Milking Apparatus; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in milking apparatus, and has more particular relationl to apparatusoperated by a vacuum to withdraw the milk from a cowsfudder.

The invention consists of the combination, with a Vacuum-tank, of a milkreceiving receptacle connected thereto and comprising an outer vacuum-chamber and an inner milk-receptacle comm unicatin g therewith and means for connecting the inner milk-receptacle with a cows udder.

The invention also consists in certain other novel construction,com bination,and arrangement of parts, all of which will hereinafter be more particularly set forth and claimed.

Inl the accompanying drawings, forming part of this specification, Figure l represents a side elevation of my improved apparatus in operation. Fig. 2 represents a central Verticalsection, partly in side elevation, of the vacuum-tank. Fig. 3 represents a detail central vertical section through the milk-recep tacle. Fig. 4 represents an enlarged detail central vertical section of one of the teatcnps. Fig. 5 represents a detail central Vertical section through the safety-Valve which is applied to the vacuum-tank and milk-receptacle, and Fig. 6 represents a detail perspective view of a series of teat-cups attached to a common receiving-pipe.

Ain the drawings represents the vacuumtank; B', the milk-receptacle; C C, the teatcups, and D D the safety-valvcs- The Vacuum-tank A is of any desired form of construction and is mounted upon suitable 'supporting-legs ou, This tank is of such strength as to fully resist the action of the vacuum created within the same and is provided upon each side near its upper edge with two upright standards a', arranged upon diametrically opposite sides of the same. .lournal-boxes a2 a2 are secured to the respective upper ends of said vertical standards and support the journal ends of a crank-shaft a3. Fly or balance'wheels a4 a4 are mounted upon the respective `ends of said crankshaft a3 outside of the journal-boxes. A belt or pul= ley wheel a5 is applied upon said shaft a3 between its crank bends and is adapted to receive a suitable power-belt, (see Fig. 1,) whereby the said shaft a3 is rotated to actuate the vacuumpumps, as hereinafter described. These vacuum-pumps d6 a6 are mounted within the top a? of the vacuum-tank and each comprises a cylinder. The lower ends of the cylinders are braced against vibration by a lateral bracing-,web as, connecting the lower ends of said cylinders to the inner walls of the vacuum-tank. Each of said cylinders 0.6 is provided at its lower end with a small semispherical valve-seat a9, upon which ismounted a spherical valve 0.410, so that any upward pressure upon said valves will cause them to open7 whereas a reverse pressure would re` seat them. Each cylinder is provided with a valved piston au, connected by piston-rod al? to a slide 0.13, mounted onvertical guides am. Each of the slides als is connected to its respective crank bend of the shaft a3 by a pitman-rod C415.

' It will be observed from the above that when the shaft a3 is operated the pistons of the Vacuum-pumps a6 will be caused to rise and fall alternately, thereby pumping the air from the tank and forming a Vacuum within 4the same.

A'cock al is mounted in the cover a7, so that when so desired the vacuum within the tank may be destroyed by permitting air to enter the same. To prevent the vacuum within the tank reaching an injurious degreeof intensity, l provide a safety-valve D, mounted Within the cover 0;"` on said tank. This valve comprises` a tube or cylinder d, provided at its upper end with interior screwb threads cl.- An apertured plug d2 is secured 95 within the said upper end of said tube d by means of screw-threads engaging the screwthreads d of said cylinder. A safety rubber valve d3, provided with a stiffening-plate d4, is mounted in the lower end of the said tube d by means of a spiral steel spring d5, which is attached to said valve and the plug d2.' This spring is so tempered that a pressure of fifteen pounds above the normal within the vacuum-tank Will expand it one inch and thus open the valve and permit air to rush into the tank until the vacuum is reduced to its normal pressure. A pipe h, preferably of galvanized iron, communicates with the top of the vacuum -tank and extends to and through different portions of the stable or shed in which the cows are stalled. Branch pipes h extend from said pipe h to the milkreceptacle B in each stall. Each of these pipes is provided at its lower end With a cock h2 and is connected to its respective outer casing of its milk-receptacle B by a flexible rubber pipe h3.

Each of the milk-receptacles B comprises an outer vacuum-tank b, a cover b', fitting air-tight upon the same by means of an annular groove b2 and a packing b3, and an inner milk-receptacle proper, b4. This latter receptacle is provided upon its bottom with supporting-legs b5, that hold the bottom of said receptacle b4 away from the bottom of the outer receptacle B, so that said receptacles will not stick together because of the vacuum within said outer receptacle. A perforated rim b is applied to the bottom of the receptacle B to assist in supporting and bracing the lower edge of the receptacle b4. The upper edge of said receptacle b4 is seated in an annular groove 57, formed in' an annular flange bs of the lid or cover cl of the receptacle B. Apertures b9 are formed in said annular -ilange bs to permit the ready ilow of air between the receptacles B and b4, respectively. The lid b of the receptacle B is provided With an angular pipe-coupling blo, seated in a recess b in said cover, a packing 1912 being applied between said coupling and said cover to make an air-tight joint at this point. The upper end of the coupling b1@ is reduced in size to provide for the attachment of a nexible conducting-pipe c.

The cover b of the receptacle B is provided with a safety-valve D and cock Z913, similar in construction to the valve D and cock am and for similar purposes. The pipe c is connected to a hard-rubber receptacle c', which receptacle is a common outlet for all of the teatcup pipes c2. Each of these pipes c2 is provided at its free end with a teat-cup C, formed of rubber and of such shape as to t snugly over the cows teat. Each of these caps is provided with a central passage c3, adapted to be opened or closed by a turning plug c4.

The operation of my apparatus is as follows: The shaft as being set in motion actuates the pumps as to create a vacuum within the immediately cause the milk to flow along through the pipes c2, receptacle c', pipe c, and into the receptacle b4, the four streams of milk consolidating in the common receptacle c. The suction is continued until the milk ceases to flow, when the safety-valve will automatically open with a loud hissing sound, thus calling the attention of the attendant, who will at once close the cock h2 and open the cock Z913, which will completely destroy the vacuum in that particular milk-receptacle. This operation will cause the teat-cups to drop away from lthe teats, but Will not in any way affect the operation of the remaining milkers, and each milk-receptacle will remain in operation until its respective indicator warns the attendant that all the milk has been withdrawn from the cows udder.

As the air is exhausted from the ou ter casing Z) the air from the inner casing b4 rushes into the same through the upper perforations until the air from said inner casing is also exhausted, the pipe connection to said inner casing in the meantime also having its supply of air exhausted. The vacuum made by this action of the pump causes the milk to flow through the pipes c, as above described, and down into the casing b4 through the nozzle 510. The specific gravity of the milk entering the said casing b4 will cause it to fall to the bottom of said casing, and thus prevent it passing through the apertures between the inner and outer casing. Y

The supply to the pipes c must of course be out off the instant the inner receptacle b4 is lled, as otherwise the milk would iow from the inner receptacle into the outer.

Having now described my invention, what I claim as new, and desire to protect by Letters Patent, is-
